Synaptic Static

You cause psychic energy to erupt at a point within range. Each creature in a 20-foot-radius Sphere centered on that point makes an INT saving throw, taking 8D6 Psychic damage on a failed save or half as much damage on a successful one.

On a failed save, a target also has muddled thoughts for 1 minute. During that time, it subtracts 1D6 from all its attack rolls and ability checks, as well as any CON saving throws to maintain Concentration. The target makes an INT saving throw at the end of each of its turns, ending the effect on itself on a success.
